Matter in this state flows and takes the shape of its container but keeps the same volume.

liquid

100

This force pulls objects toward Earth.

gravity

Eye color and natural hair color are examples of these traits passed from parents to offspring.

inherited trait

100

This star appears brighter than others because it is closest to Earth.

the Sun

100

This pattern occurs when the Moon appears to change shape in the sky over about a month. 

moon phases

200

This phase change happens when a liquid becomes a gas.

evaporation (or vaporization)

200

If you push a box to the right with 10 N and someone pushes it left with 10 N, the box will likely do this.

stay still (no change in motion)

200

A baby turtle moving toward the ocean right after hatching is an example of this type of behavior.

instinctual behavior

200

How many stars are in our solar system?

one

200

What is the main cause of ocean tides?

the moon's gravitational pull

300

Color, texture, and hardness are examples of these kinds of properties.

physical properties

300

In an investigation, scientists collect this to support their conclusions.

evidence (data)

300

Differences in traits like fur color or height within a species are called this.

variations

300

This force keeps planets moving in their orbits around the sun.

gravity

300

What are two results of Earth's rotation on its axis?

day and night, stars and sun appear to move across the sky, time zones

400

Rust forming on metal is an example of this kind of change.

chemical change

400

This force occurs when two surfaces rub against each other and slows objects down. 

friction

400

A characteristic that helps an organism survive in its environment is called this.

adaptation

400

This is the name for the path a planet follows as it travels around the Sun. 

orbit

400

What two things cause Earth's seasons?

Earth's tilt and Earth's revolution around the sun

500

This scientific law explains that matter cannot be created or destroyed.

Law of Conservation of Matter

500

A student pushes a toy car harder during an experiment. The car travels farther and faster than before. What does this investigation show about the relationship between force and motion?

A stronger force causes a greater change in motion.

500

Even though all zebras belong to the same species, their stripe patterns are slightly different. This shows this concept.

variation within a species

500

Where in the Milky Way galaxy is Earth located?

on one of the spiral arms

These star patterns appear to move across the sky during the year as Earth orbits the sun.
